Abstract
In the field of digital image processing [1], noise removal is always a critical process. In this paper we proposed an enhanced method of image de-noising. The purpose of this new method is to improve the signal to noise ratio (SNR) of de-noised image and get more better image, especially when image corrupted by high noise density. We improved the median filter algorithm, and get comparatively better results than previous methods. The mathematical analysis shows that this process improve the PSNR [2](Peak signal to noise ratio) at high density noise level. It also reduces the complexity of calculation because noise detection and noise removal both processes are performing simultaneously. This method produce better image without blurring and also preserve the edge and fine details of image.
